Hvac Licensing in Kentucky

Kentucky HVAC License Verification

To legally perform Heating, Ventilation, Air Conditioning, and Refrigeration (HVAC) work in the Commonwealth of Kentucky in 2026, individuals must hold a valid license issued by the Kentucky Department of Housing, Buildings and Construction (DHBC) – Division of HVAC. This state agency is the primary governing board responsible for regulating and licensing the HVAC industry to protect citizens' lives and property. The DHBC offers three main credential types: Apprentice, Journeyman HVAC Mechanic, and Master HVAC Contractor. An Apprentice must be at least 18 years old and registered, working under the direct supervision of a licensed journeyman or master HVAC professional. To become a Journeyman HVAC Mechanic, applicants must document a minimum of two years (3,000 hours) of experience under a licensed master HVAC contractor or complete an approved training program with one year of on-the-job training. This is followed by passing a state-administered journeyman examination with a score of 70% or higher. The highest credential, the Master HVAC Contractor License, requires an additional two years of experience as a licensed Kentucky journeyman working under a Master HVAC Contractor. Master candidates must also pass a comprehensive examination that includes a business and law section, achieving a minimum score of 70%.

The Kentucky Department of Housing, Buildings and Construction provides an online verification tool for potential clients or employers to confirm an HVAC license by searching by permit number, license number, address, or name.

Insurance and Bonding Mandates

Kentucky mandates specific insurance requirements for HVAC professionals, particularly for Master HVAC Contractors. These individuals must carry and provide proof of general liability insurance with a minimum coverage of $500,000, along with property damage insurance in the amount of $300,000. The Kentucky Department of Housing, Buildings and Construction must be listed as a certificate holder on the insurance documentation. Furthermore, any HVAC business operating in Kentucky with one or more employees is required to secure Workers' Compensation insurance. While statewide surety bond requirements for HVAC contractors are not universally specified in the same manner as insurance, some local jurisdictions, such as Louisville and Lexington, may have their own bonding mandates.

Permitting and Local Regulations

Kentucky has implemented a statewide HVAC permitting and inspections program for both residential and commercial construction, which began in 2011. A permit is required for all new installations, significant modifications, and replacements of HVAC systems. It is crucial to note that permits are not required for replacing a single component of an HVAC system. Critically, only licensed Master HVAC Contractors are authorized to apply for and obtain these necessary permits. Local governing entities are permitted to establish their own HVAC inspection and permitting programs, provided they align with state requirements. For instance, within Louisville Metro, contractors must possess both a Kentucky HVAC Master License and a specific Metro HVAC Contractor's License, and all required permit documentation must be submitted and approved before any work commences.
